changes

add energy bars that are exactly in sync in y with applet
hide the text and energy bars originally there by Fu-Kwun Hwang
added usual control at the bottom panel
add stagetext to allow make sense of motion
if(stage==0){ // moving in circular motion on the uptrack
else if(stage==1){ // moving in circular motion on the circletrack
else if(stage==2 ){ // moving in linear motion on the straight bottom track
else if(stage==3){//free fall

bug:
found a bug in nf in stage 1 the number did not make sense

16 September 2011
redesign the mg, R at and ar, omega and alpha bars to show
fix some bugs inside
introduce mass m
add values cta and v and auto-scale for difficult to get views

to do some issues when R = small the view is to the left too much
